This is so way beyond me. But beautiful to look at. Congrats on figuring all this out. So complex for my level of patience.

Tonight I've been getting image time on IC1318, IC1318B which are large nebulous regions, and NGC6910 which is a nice little open cluster nearby. The full frame of the 5D III is JUST AMAZING. It's more than twice as big as the 7D frame, and the images, once processed, are pretty stunning.
This is my first pass at processing a single-frame image of North America and Pelican nebulas in Cygnus, near the top star. Not entirely satisfied with it...I'd like to stretch it more, bring out some more detail, but I need to get a better handle on noise and color correction (a lot of the color correction routines end up making things noisier as they end up nuking most of the green color channel.)
Beautiful image jrista. What 'scope or lens are you using?jrista said:More Cygnus. I really love this region of sky, it's amazing.

Usually, getting this entire region requires a 4-panel mosaic with the smallish CCD sensors you can usually find for a reasonable price. Only those with the big money can get comparable full frame CCD cameras...which usually cost about $10,000 or more. I've got a cold box in the works for the 5D III, which should help get my dark current levels under control, and help me get better, deeper, less noisy subs (although still not as good as a cooled CCD...my cold box will probably only get me down to around -10°C, where as a good CCD can get you down to -25°C. With dark current doubling/halving every 5.8°C, a CCD is going to be about about 2.6x less noisy (and even better than that, really, as a mono CCD has a higher fill factor, no sparse color spacing, and CCDs designed for astro tend to have lower dark current to start with...)

niteclicks said:Thanks Jrista for starting this thread it made finally get started setting my stuff back up. I haven't set my mount up in 4 years, moved and a permanent setup has always been on the to do list (but at the bottom). The long 4th weekend gave me time to unpack and setup temporally to tryout were I might want a permanent mounting. This is a wide field (about 75% crop) of the area around the Trfid and Lagoon nebulae. This is about the southern edge of my usable sky were I have it now. 84 frames at 800 iso, 30sec , 300 2.8l is , 5DIII, on an Atlus EQ-G processed with Images Plus. Alignment needs work but it has mostly been cloudy since.

Nice... Proof that you don't need insane amounts of gear to get started....kkelis said:Dont know if you can call this deep sky astrophoto but here is my version of andromeda
